在本公开的描述中,需要说明的是,术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本公开和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本公开的限制。此外,术语“第一”、“第二”、“第三”仅用于描述目的,而不能理解为指示或暗示相对重要性。
由于大尺寸显示屏信号线的增加,需采用两颗IC设计,导致了FPC连接器PIN(引脚)数的增加;但是常规项目单个连接器无法满足需求:因为单个连接器最多具有60PIN,双IC设计的引脚的数量超过了60PIN;需采用两个连接器设计。而每次点灯需要同时扣接两个连接器,才能正常点灯,对产线生产及内部验证带来较大的困难。
针对上述技术问题,本实施例中,一种触控显示装置,包括显示面板和与显示面板连接的柔性线路板3,所述柔性线路板包括显示功能区和触控功能区,所述显示功能区通过第一连接器4连接所述触控显示装置的控制主板,所述触控功能区通过第二连接器5连接所述触控显示装置的控制主板。

所述显示面板可以是COP(Chip on panel)结构,也可以是COF(Chip on film)结构。本实施例中示例性的,参考图4,所述显示面板和所述柔性线路板3之间还设置有覆晶薄膜100,所述覆晶薄膜100上设置有显示IC 6,所述柔性线路板3将所述显示IC的信号与所述触控显示装置的主控板的CPU连接。
所述驱动电极信号线和所述感应电极信号线通过所述覆晶薄膜上的走线连接至所述柔性线路板上的所述触控IC。
所述触控显示装置的驱动方法包括:
连接所述第一连接器,进行显示操作;
连接所述第二连接器,进行触控操作。
无需同时连接所述第一连接器和所述第二连接器即可实现相应的操作,即需要进行触控检测等触控相关的操作时,只需连接所述第一连接器即可实现,而需要进行画质检测等与显示相关的操作时,只需连接所述第二连接器即可,使得触控和显示分开独立进行控制,降低了操作难度,实现了分别点灯的便捷和产线作业的自动化。
以上所述为本公开较佳实施例,需要说明的是,对于本领域普通技术人员来说,在不脱离本公开所述原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本公开保护范围。
